Description

Technical Field

[0001] The invention belongs to the field of cargo conveying equipment, and specifically relates to automatic conveying equipment for clothing warehouses, in particular to a bending conveyor. Background Art

[0002] At present, in clothing production, automated storage systems have become a convenient and time-saving working mode, but the existing storage system conveyors are bulky and have high equipment costs. They need to be operated through cylinders or in conjunction with power sources such as hydraulic cylinders. They are complicated to install and take up a large space. They cannot be used in small production workshops, resulting in a narrow scope of application and high equipment costs.

[0003] In order to solve the above problems, the industry invented the unpowered roller screw conveyor, but the existing screw conveyors on the market are basically simple single tracks or parallel double tracks. In the process of transporting goods, this type of equipment uses the rotation of the rollers to drive the goods to move under the action of the rollers. If the mass of the goods is large, the goods and the rollers form rolling friction, and the friction force is relatively small, then the goods will rush out of the discharge port at a high speed, causing the loss of goods and even causing injuries to people. In addition, due to the shape of the spiral conveyor belt, it is difficult for large-volume cargo boxes to rotate during the rotation process, causing the goods to stop on the conveyor and fail to complete the transportation work.

[0004] Chinese patent CN 106347933 A discloses a spiral conveyor, including a fixing device and a guide system, wherein the fixing device includes a fixing column located at the center of the device and a supporting column at the bottom, wherein a fixing rod is spirally arranged on the outside of the fixing column, and the spacing between adjacent fixing rods is the same, and the guide system includes a motor and a guide rail, wherein the guide rail is fixed on the fixing rod and is in a spiral ascending shape, and a high-position material inlet and outlet is arranged at the upper end of the guide rail, and a low-position material inlet and outlet is arranged at the lower end, a chain plate is arranged on the surface, guardrails are arranged on both sides, and a track is arranged inside, wherein a chain is connected inside the track, and the upper part of the chain is fixed parallel to the chain plate, and the chain is operated under the action of the motor, and drives the chain plate to complete the up and down transportation operation. The conveyor described in the application drives the chain plate to transport goods through two parallel chains, and during the transportation process, the goods move forward together with the chain plate. During the rotation stage, the chain plates need to overlap and tilt to realize the rotation and transmission of goods, which results in a slow conveying speed and low flexibility. On the other hand, the chain plates overlap during the rotation process and the surface formed by the chain plates is uneven, so goods are easily piled up on the chain plates, which not only damages the goods but also easily causes transportation interruptions, affecting the transportation efficiency. Furthermore, during the entire transportation process, the entire chain plate of the conveyor needs to be driven by the motor to operate, which consumes a lot of energy.

[0005] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a conveyor which occupies a small space, has a simple and stable structure, is easy to install, has strong conveying flexibility, high conveying efficiency, low energy consumption, and a wide range of applications.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a bending conveyor, which includes a fixing device and a guiding system fixed on the fixing device, wherein the guiding system includes a motor and a guide rail, wherein the guide rail includes a spirally ascending arc area, wherein rollers are rotatably installed in the guide rail, wherein the rollers include a first roller and a second roller, wherein the length of the first roller is greater than that of the second roller.

[0008] Furthermore, the arc-shaped area includes a first spiral track and a second spiral track connected in an S-shaped smooth transition, and the first spiral track and the second spiral track are three-row spiral conveying tracks.

[0009] Furthermore, the first spiral track includes, from inside to outside, a first inner track, a first middle track and a first outer track with gradually increasing radii, and second rollers are rotatably installed in the first inner track, the first middle track and the first outer track.

[0010] Furthermore, the second rollers in the first inner track, the first middle track and the first outer track are arranged alternately with gaps therebetween, and the projections of the second rollers on the horizontal plane are distributed along the radial direction of the circle.

[0011] Furthermore, the second spiral track includes a second inner track, a second middle track and a second outer track with successively decreasing radii, and second rollers are rotatably installed in the second inner track, the second middle track and the second outer track.

[0012] Furthermore, the second rollers in the second inner track, the second middle track and the second outer track are arranged alternately with gaps therebetween, and the projections of the second rollers on the horizontal plane are distributed along the radial direction of the circle.

[0013] Furthermore, the first inner rail and the second inner rail are connected in an S-shaped smooth transition and are driven by an independent motor; the first middle rail and the second middle rail are connected in an S-shaped smooth transition and are driven by an independent motor; the first outer rail and the second outer rail are connected in an S-shaped smooth transition and are driven by an independent motor.

[0014] Furthermore, the guide rail also includes a first straight rail and a second straight rail, the first straight rail and the second straight rail are single-row conveying rails, and parallel first rollers are rotatably installed in the first straight rail and the second straight rail. The first straight rail is a rail with a slope, and the second straight rail is a horizontally arranged rail.

[0015] Furthermore, the fixing device includes a middle column located at the center of the equipment and a support frame at the bottom, the support frame includes a foot frame located at the bottom of the conveyor for supporting the guide rail and a base located at the lower side of the middle column, and the middle column is supported on the ground by the base.

[0016] Beneficial technical effects:

[0017] First, the second spiral track and the first spiral track of the bending conveyor described in the present invention include three rows of tracks that are connected in correspondence and arranged in an interlaced manner, and each of the three rows of tracks is independently driven by a motor, which enables the three rows of tracks to run at synchronous or asynchronous speeds and in the same or opposite directions. The widths of the tracks can be the same or different. The design of the three-row staggered tracks can adjust the force distribution of the goods by using the asynchronous staggered operation of the three tracks during the turning process of the cargo box transportation, thereby increasing the transportation flexibility of goods of different weights, shapes, and volumes, so that all kinds of goods can be smoothly transported between the running tracks, with high transportation efficiency and a wide range of applications.

[0018] Second, different conveying tracks are driven by independently set motors. Whether the motor of each track is running and the running speed can be adjusted according to the transportation needs. When there are goods to be transported on the track, the corresponding motor is operated to transport the goods; when there are no goods to be transported on the track or the goods have been transported to the next conveying track section, the motor of the corresponding track can stop running to reduce energy consumption.

[0019] Third, the bending conveyor described in the present invention has a single bending track as its transport track, which can reduce the floor space on the one hand; on the other hand, it is easy to be used in combination with existing production lines, and is particularly suitable for small production workshops.

[0020] In summary, the bending conveyor provided by the present invention occupies a small space, has a simple and stable structure, is easy to install, has controllable conveying direction and conveying speed, has strong flexibility, high conveying efficiency, low energy consumption, and a wide range of applications.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-4 As shown, the present invention provides a bending conveyor, the conveyor includes a fixing device 1 and a guide system 2, the guide system 2 is fixed on the fixing device 1, the fixing device 1 includes an intermediate column 11 located at the center of the device and a support frame 12 at the bottom. The support frame 12 includes a foot frame 121 located at the bottom of the conveyor for supporting a guide rail 21 and a base 122 located at the lower side of the intermediate column 11, and the intermediate column 11 is supported on the ground by the base 122. The intermediate column 11 is supported by the base 122, which can make the conveyor more stable and firm. The guide system 2 includes a motor and a guide rail 21, the guide rail 21 is fixed to the outside of the intermediate column 11, and guardrails 3 are arranged on both sides of the guide rail 21. The guide rail 21 includes a spirally ascending arc area, and rollers are rotatably installed in the guide rail 21. The rollers include a first roller 215 and a second roller 216, and the length of the first roller 215 is greater than that of the second roller 216.

[0030] Further, if Figure 1-4 As shown, the arc-shaped area includes a first spiral track 212 and a second spiral track 213 connected in an S-shaped smooth transition. The first spiral track 212 and the second spiral track 213 are three-row spiral conveying tracks.

[0031] Furthermore, the guide rail 21 includes a second straight rail 214, a second spiral rail 213, a first spiral rail 212 and a first straight rail 211 which are connected in sequence, and the heights of the second spiral rail 213, the first spiral rail 212 and the first straight rail 211 gradually increase. The intermediate column 11 and the guide rail 21 are connected by a connecting rod 13.

[0032] like Figure 1-4 As shown, the first straight track 211 is a single-row conveying track connected to the upper conveying line at one end, and the other end of the first straight track 211 is connected to the first spiral track 212. The first straight track 211 is a straight track with a slope, and the height gradually decreases from the end connected to the upper conveying line to the end connected to the first spiral track 212. This allows the first straight track 211 to be used as a feeding end, and the first straight track 211 can use its own gravity to obtain a part of the power for downward movement, so as to reduce the power required for the first straight track 211 to transport goods. A number of first rollers 215 arranged in parallel and at equal intervals are rotatably installed in the first straight track 211. The first straight track 211 is driven by an independent motor. The first straight track 211 is driven by an independent motor so that the first straight track 211 can be selected to operate or stop according to transportation needs. Further, the operation speed of the first straight track 211 can be flexibly adjusted according to transportation needs.

[0033] like Figure 4 As shown, the two ends of the first spiral track 212 are connected to the first straight track 211 and the second spiral track 213 respectively. The first spiral track 212 is a track that spirally rises from the end connected to the second spiral track 213 to the end connected to the first straight track 211. Preferably, the first spiral track 212 is a 270° track that spirally rises. Further, the first spiral track 212 is concentrically arranged with the middle column 11. The first spiral track 212 is a three-row conveying track, and includes a first inner track 2121, a first middle track 2122 and a first outer track 2123 with gradually increasing radii from the inside to the outside. A plurality of second rollers 216 are rotatably installed in the first inner track 2121, the first middle track 2122 and the first outer track 2123. The second rollers 216 in the first inner track 2121, the first middle track 2122 and the first outer track 2123 are interlaced and arranged, and the projection on the horizontal plane is distributed along the radial direction of the circle. The setting of the three-row conveyor track makes the conveyor described in the present application more flexible, especially when large goods pass through. The force conditions of different parts of the goods can be adjusted by adjusting the rotation speeds of the first inner track 2121, the first middle track 2122 and the first outer track 2123, so that different parts of the goods obtain different angular velocities, which can effectively prevent the goods from getting stuck in the spiral track of the conveyor, making the transportation of goods smoother.

[0034] like Figure 1-4 As shown, the two ends of the second spiral track 213 are respectively connected to the second straight track 214 and the first spiral track 212, and the second spiral track 213 is a spiral ascending track, and the second spiral track 213 is connected to the first spiral track 212 in an S-shaped smooth transition. Preferably, the second spiral track 213 is a spiral ascending 90° track. The setting of the first spiral track 212 and the second spiral track 213 can realize a 180° single bend in the conveying direction, and the goods are transported by a 180° single bend, so that the conveyor described in the present application is easy to be used in conjunction with the existing production line. Furthermore, the conveyor with the single-bend conveying track, its first straight track 211 is supported above the second straight track 214 by the tripod 121, that is, the first straight track 211 no longer needs to occupy a separate area, which can further reduce the equipment footprint, and then reduce the space occupied by the equipment, so that the conveyor described in the present application is particularly suitable for use in small production workshops. The second spiral track 213 is a three-row conveying track, including a second inner track 2131, a second middle track 2132 and a second outer track 2133, whose radii increase and decrease successively. The second inner track 2131, the second middle track 2132 and the second outer track 2133 have a plurality of second rollers 216 rotatably installed therein. The second rollers 216 in the second inner track 2131, the second middle track 2132 and the second outer track 2133 are arranged alternately with each other in between, and the projections of the second rollers 216 on the horizontal plane are distributed radially along the circle. The two ends of the second inner rail 2131 are connected to the first inner rail 2121 and the second straight rail 214 respectively, the two ends of the second middle rail 2132 are connected to the first middle rail 2122 and the second straight rail 214 respectively, the two ends of the second outer rail 2133 are connected to the first outer rail 2123 and the second straight rail 214 respectively, the second inner rail 2131 and the first inner rail 2121 are connected in an S-shaped smooth transition, and are driven by an independent motor; the two middle rails 2132 and the first middle rail 2122 are connected in an S-shaped smooth transition, and are driven by an independent motor; the second outer rail 2133 and the first outer rail 2123 are connected in an S-shaped smooth transition, and are driven by an independent motor. The three columns of conveying tracks of the second spiral track 213 and the first spiral track 212 correspond to and are connected to each other, and are driven by independent motors respectively, so that the three columns of conveying tracks can run at synchronous or asynchronous speeds, and run in the same or opposite directions. During the cargo transportation process, the asynchronous and staggered operation of the three columns of conveying tracks can increase the adaptability of the conveyor described in the present application to cargoes of different weights, shapes, and volumes, so that cargoes of various weights can be smoothly transported between the running tracks.

[0035] like Figure 1-4As shown, the second straight track 214 is a single-row conveying track connected to the conveying line below, and a plurality of first rollers 215 arranged in parallel and at equal intervals are rotatably installed in the second straight track 214, and the second straight track 214 is a horizontally arranged straight track. Preferably, the second straight track 214 is driven by an independent motor. The second straight track 214 is driven by an independent motor and is arranged horizontally, so that when the second straight track 214 is used as the goods output end, the movement speed of the goods after being output from the second spiral track 213 can be adjusted according to the second straight track 214 as needed and then output to the conveying line below.

[0036] In summary, it is not difficult to conclude that: First, the second spiral track and the first spiral track of the bending conveyor described in the present invention include three rows of tracks that are connected in correspondence and arranged in an interlaced manner, and each of the three rows of tracks is independently driven by a motor, which enables the three rows of tracks to run at synchronous or asynchronous speeds, in the same or opposite directions, and the width of the tracks can be the same or different. The design of the three-row staggered track can adjust the force distribution of the goods during the turning process of the cargo box transportation by using the asynchronous staggered operation of the three tracks, increase the transportation flexibility for goods of different weights, shapes, and volumes, and enable all kinds of goods to be smoothly transported between the running tracks, with high transportation efficiency and a wide range of applications. Second, different conveying tracks are driven by independently set motors to operate, and whether the motors of each track are running and the operating speed can be adjusted according to the transportation needs. When there are goods to be transported on the track, the corresponding motors are operated to transport the goods; when there are no goods to be transported on the track or the goods have been transported to the next conveying track section, the motors of the corresponding tracks can stop running to reduce energy consumption. Third, the bending conveyor described in the present invention has a single bending track for its transport track, which can reduce the floor space on the one hand; on the other hand, it is easy to be used with the existing production line, and is particularly suitable for small production workshops. In short, the bending conveyor provided by the present invention occupies a small space, has a simple and stable structure, is easy to install, has controllable transport direction and transport speed, is highly flexible, has high transport efficiency, low energy consumption, and has a wide range of applications.

[0037] It should be pointed out that, for those skilled in the art, several improvements and modifications may be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
